JupyterLab 4.1¶

Diagrams in Markdown¶

Matching GitHub-Flavoured Markdown, JupyterLab 4.1 now supports Mermaid 2 diagrams. To create a mermaid diagram use the mermaid language specifier for a code block in a markdown cell or document, for example:

flowchart LR

A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]

Inline completer¶

In [2]:
def factorial(n):
    result = 1
    for num in range(2, n + 1):
        result *= num
    return result
In [ ]:
def factorial(n):
    result = 1
    for num in range(2, n + 1):
        result *= num
    return result

Opening files from tracebacks¶

In [3]:
import custom; custom.div(1, 0)

---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
Cell In[3], line 1
----> 1 import custom; custom.div(1, 0)

File ~/git/jtpio/2024-04-29-jupyter-open-studio-day/notebooks/custom.py:2, in div(a, b)
      1 def div(a, b):
----> 2     return a / b

ZeroDivisionError: division by zero

Error indicator in the table of contents¶

Plugin Manager¶

Virtual scrollbar for notebook in windowed mode¶

JupyterLab 4.2¶

Workspace UI¶

Full notebook windowing mode by default¶

Improved Shortcuts Editor¶

Among the numerous improvements and bug fixes for the keyboard shortcuts editor:

  • it is now possible to remove the default shortcuts,
  • shortcuts are correctly sorted when using a language pack,
  • shortcuts with different arguments are now correctly displayed as individual entries.

Dark high contrast theme¶

Notebook 7¶
